Useful Diagnostic Tools:

The Sedovnou spark plug ignition tester is ideal for small engines and vehicles. It allows for quick and straightforward diagnostics of ignition issues, outboard motor problems, or faults in the fuel delivery system.

Easy to Use:

Connect the spark plug tester between the spark plug and the plug wire. Start the engine, and if sparks are present, the in-line spark tester will illuminate to reflect the spark. For no-start conditions, have a friend crank the engine while you observe the tester for spark indications.

Superior Material:

The tester is constructed with a rubber sheath, high-quality, high-temperature-resistant wire, and environmentally friendly acetate fiber plastic. It performs reliably in both high and low-temperature environments.

Light Indication:

The spark plug checker uses a bright white light to indicate a healthy spark, while a dim light signals a weak coil or plug. This visual feedback ensures you remain safe from electric currents and quickly identifies inconsistencies.

Applications:

This tester is suitable for all internal and external combustion engines, including cars, trucks, motorcycles, lawnmowers, chainsaws, trimmers, snow blowers, and generators.
